The intensity of the infiltrating eosinophil response was graded on an arbitrary scale of 0-4 (0 = no response; l=mild response, 2 = moderate response; 3 = strong response; 4 = sever response, as judged by the density of leukocytes infiltrating to the peribronchial and peribronchiolar tissues).
Map of Virginia with the Northern Neck region shown in red. The Northern Neck is the northernmost of three peninsulas (traditionally called necks in Virginia) on the western shore of the Chesapeake Bay in the Commonwealth of Virginia (the other two are the Middle Peninsula and the Virginia Peninsula).
This peninsula is bounded by the Potomac River on the north and the Rappahannock River on the south. It encompasses the following Virginia counties: Lancaster, Northumberland, Richmond, and Westmoreland. The inclusion of King George County in the Northern Neck varies among commentators. Historically, the grant for the Northern Neck included all land between the Rappahannock and Potomac rivers, including far upstream of King George County â some 5 million acres.
